SPECIFICATION forming part of LettersPatent No. 654,353, dated July 24, 1900..

` Application filed March l0, 1900. Serial No. 8,155. (No model.)

T0 all whom t may concer/t: v

Be it known that I, THOMAS OLDHAM, a

citizen of the United States, and a resident of Leipsic, in the county of Orange and State of Indiana, have invented a new and useful lmprovement in Oultivators, of which the fol light and regular and so that the machine may be conveniently and readily managed.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal vertical section taken substantially on the line l 1 of Fig. 2. Fig. 2 is a plan view, partsbeing in horizontal section, which section is taken practically on the line 2 2 of Fig. 1. Fig. 3 is a vertical transverse section taken practically on the line 3 3 of Fig. 1. Fig. 4 is a side elevation of a portion of a beam and a side elevation of one of the devices employed for holding a barrow-tooth or shovel in connection with the beam. Fig. 5 is a section taken practically on the line 5 5 of Fig. 4, and Fig. 6 is a section taken on the line 6 6 of Fig. 5.

The frame A of the machine is preferably tapered at the front, so that its sides at that portion are inclined rearwardly in opposite directions, and the frame is provided with an upright extension 10 near the rear and with a rear circular portion 11. At the front portion of the frame projections 12 are formed, in which a vert-ical shaft 13 is mounted to turn, and thisf shaft carries a wheel 14. The shaftu is provided between the projections 12 with a clevis 15, in which apertures 16 are produced. The shovels or teeth of the implement may be made toenter the ground to a greater or less extent, according to the aperture in the clevis, into which the draft device is introduced. At or near the central portion of each side of the frame an upright 17 is formed, having a` longitudinal slot 1S in vits upper portion, and these uprights 17 are usually connected at the top by a cross-bar 19, as shown in Fig. l. A cross bar or plate 2O connects the frame A at the rear of the uprights 17, `and upon this cross bar or plate 2O a ver tical yoke 2l is centrally secured.

.A platform 22 extends from one side pro; jection 10 of the frame to the other, and an auxiliary frame B is pivotally connected with the said platform through the medium of a suitable pin located at the center of the platform. This frame B consists of a horizontal body-bar 23, downwardly-extending arlns 24.- at the end portions of the said body-bar, and a yoke-section 25, which is connected with the downwardly-projecting arms 24 at the lower ends of said arms, and the said yoke is located slightly at the rear of the cross bar or plate 20. The yoke-section 25 of the aux= iliary frame B is provided at its center with a forwardly-extending member 26, which is carried beneath and beyond the cross bar or plate 2O and is provided at its outer end with a friction-roller 27. This friction-roller 27 is made to travel upon a curved horizontal track 28, extending from side to side of the main frame, and serves to guide the auxiliary frame B in its movement, as .the auxiliary frame B is adapted to be turned to the right or to the left. This movement ofthe auxiliary frame is acco mplished by means of a crank 29, forming a portion of a shaft 30, which crank enters a suitable slot in the forward projection 26 from the auxiliary frame B, while the shaft 30 extends upward through and is journaled in the vertical yoke 2l, forming a portion of the main frame of the machine, and the shaft 30 is preferably providedat its upper end with a pivoted handle 3l, extending in direction of the drivers seat 32, the latter being mounted upon the platform 22. The handle 3l of the shaft 30 is so pivotedthat it may be raised up and carried out of the way of the drivers seat when necessary. Suitable braces 26 are provided for the forward portion of IOO mental tracks 35, located at each side of the `frame of the machine.

Thus it will be observed that the machine is supported by the forward wheel 14 and the rear roller 32a and is guided by moving the rear roller 3,2 to the right or to the left, as occasion may demand.

A cultivator-frame C is carried by the main frame A of the machine. This cultivator- -frame C @OnsiSS of two outside beams 36,

which are at angles to each other, and a centrai-beam 37. These beams connect at their forward portions, and where they connect an eye 3 8 is formed, which eye receives a shaft or pin 39, located at the forward central portion ofthe main frame, being held in a bracket 40, Whih extends both above and below said main frame, as particularly shown in Fig. 1. The outer beams of the cultivator-frame C are ,connected by links 41 or their equivalents shown Figl,

with a drag D. This drag consists of side bars 4,2 and bottom plates 43, which bottom plates are attached to the side bars and eX- tend downward and rearward, being adapted at their lower edges for engagement with the ground, as shown in Fig. 1. The cultivatorfrom@ C and the drag D are lfaied and 10W- ered bythe following mechanism: A shaft 44 is mounted qto turn in the uprights 17, and between the said uprights toothed segments 4,5 are seonred to the said shaft 44, one of which segments .4,5 is provided with an attached levei- 46, having a Isuitable thumb-latch for engagement with a rack 47. A shaft 49 is located above the Shaft 44, and the Shaft 49 is adapted to Slide in the `slots ,18 of the uprishts 17. The shaft 49 is provided near each -end with toothed segments 4S, secured thereto, and the teeth of the segments 48l are arranged for engagement with the teeth of the segments 4 5 on the shaft 44. The couvexed surfaces of these segments are in opposition, as A pulley 50 is secured upon the vertically-adjustable shaft 49, and an @finalizing-rod 5l`is made to rest upon the said pulley, theinner end of which rod is pivotally attached to the upright yoke 21 of the mainframe of the machine, as shown in Fig. 1, and the forward end of the equalizing-rod 5l, which extends downward beyond the pulley 50, is connected by a link 52 and a chain 53 or their equivalents with the upper central portion of the cultivator-frame C.

The cultivator-frame is guided in its upward movement by means of uprights a', car7 ried from the ends of a cross-bar a', attached to the cultivator-frame at or near its center, and a rod c2 is passed through these guides o,

while a link-and-.chain connection 55 is provided between `the rod a2 and the verticallyadjustable shaft 49. "Links 56 and suitable lengths of chain are also employed to connect the rear end portion of the drag D with the equalizing-bar 5l, so that as the shaft 49 is raised or lowered by manipulating the lever 46, which is convenient to the drivers seat, both the drag and the cultivator-frame may be raised orlowered, as occasion may demand.

Guards 57, in the form of runners, are pivoted at their forward ends to the outer side surfaces of the main frame A, and the free ends of these guards or runners are connected by links 5S or their equivalents with the end portions of the vertical shaft 49, so that these guards or runners are raised or lowered simultaneously with the corresponding move.- ment of the cultivat0r=frame and drag The cultivator teethl or shovels, whichever are to be employed, are attached to the beams of the cultiVator-franie in a peculiar manner or so that they maybe adjusted as to inclination and will yield when they strike a ,stone or similar obstruction, which might otherwise break them. To this end clips 59 are secured upon the beams of the ,cultivatorfframe as shown in Fig. 5, and each .clip is provided with members 60 and 61, which QXIGIJ bQloW the beam, as is shown also in Fig. l5. A bolt 62 is passed through these downwardly-eig: tending members of the clip, and a receiililg plate 64 is mounted upon the outer end of each bolt 62, held in position by suit-able collars on said bolts 62 and by nuts 6,3. The re,- ceivingeplates are free to rock on their sup: porting-bolts 62. Each receiving-plate iSl pro-` vided with an upper enlarged section or head 65, in which a transverse curved slot 66 is produced, and a short tubular bolt .67 is passed through the slot 6ol in each receivingfplate, while a nut 68 is located at the outer end of each of the tubular bolts 67, as shown in Figs. 4, 5, and 6. A spring 694 is coiled around each bolt 62 between the downwardly-extending members of the clips 59, and each spring 59 has bearing against one member of the clip, while the other end of the spring is car..- ried upward and is passed .through the bore in the tubular bolt 67, as is principally shown in Figs, 4, 5, and 6. that the spring 69 serves to control or regnlate the position of the receiving-plate with which it is connected, and when the said plate has been adjusted to carry the shovel or tooth received by it into the ground should the tooth or shovel engage with a stone or other obstruction which it cannot remove the spring 69 will give, and said tooth or shovel willthus be preserved from injury. A rabbet ,or recess 7l is made inthe inner face of thehead ofeach receiving-plate, and the inner wall of this re,- cess or rabbeted surface 71 is provided with teeth 72, which teeth are adapted to engage with corresponding teeth 70, producedupon the head of the tubular bolt 67, so that the said l'OO IOS

IIO

Thus it will be observed tubular bolt may be adjusted in the head of the receiving-plate to which it belongs to impart more or less inclination to said receiving-plate. Each receiving-plate is provided below its pivot with a socket, and this socket receives a shank 73, having one end sharpened, so that it may be used as a tooth, and the shank is adjustably secured in the socket by a set-screw 74E or its equivalent, and at one end of cach shank '73 a cultivator-shovel 75 is secured in any suitable or approved manner.

It is frequentlyv necessary that a brake should be provided for the roller 32a. To that end a shaft 76 is journaled in a bracket 77, extending downward from the upper or body member 23 of the rear auxiliary frame B, and this shaft 76 is provided with an attached foot-lever 7S and with a shoe 79, arranged for engagement with the roller 32a, when the foot-lever is depressed; but normally the shoe is held out of engagement with the said roller through the medium of asprin g 80, coiled around the shaft 7G, as is shown in Fig. 3. The roller may be readily removed by withdrawing its shaft, and the cultivatorframe and drag may likewise be readily detached when not required.
